MACHINE.

SPECIFICATION forming part of Letters Patent No. 436,784, datedSeptember 23, 1890.

Application filed March l5, 1890.

.To all whom it may concern:

Be it known that I, JOHN G. IIODGSON, a citizen of the United States,residing in Maywood, in the county of Cook and State of Illinois, haveinvented a new and useful Im- Y provement in Crimping-lvlachines forSheetj Metal Cans, of which the following is a speci- A cation.

Myinvention relates to machines for crimping sheet-metal cans or othervessels.

The object of my invention is to provide what I term a universalcrimping-machine, or a machine which may be readily adapted to crimpcans of different sizes or shapes.

My invention consists in the novel devices and novel combinations ofparts and devices herein shown and described, and more particularlypointed out in the claims.

In the accompanying drawings, which form a part of this specication,andin which similar letters of reference indicate like parts, Figure l is aside elevation of a machine embodying my invention. Fig. 2 is a frontend view. Fig. 3 is a rear end view or sectional elevation looking fromthe line 3 3 of Fig. 1. Fig. 4 is a detail sectional View showing thevertically-adj ustable slide to which the rollerframe is pivoted. Fig. 5is a section on line 5 5 of Fig. l. Fig. G is asect-ion on line 6 G ofFig. 5. Figs. 7 and 8 are sectional views showinga can before and afterthe crimping operation.

In the drawings, A represents the frame of the machine.

I3 is .the lower crimping-roller shaft journaled in fixed bearings B Bon the frame of the machine. v

C is the driving wheel. The revolving shaft B is furnished with acrimping-roller b, adapted to be inserted within the can. The roller l)is detachably secured upon the end of the shaft B, preferably by meansof screwthreads o', so that this crimping-roller may be removed andreplaced by others of a different diameter or shape, according to theparticular size of the can and shape of crimp designed to be operatedupon or produced. The crimping-roller h is or may be furnished withabeveled flange b2. rIhe form of this 5o flange will of course vary,according to the particular shape of seam desired to be crimped SerialNo. 344,017. (No model.)

The shaft B is also, preferably,

or produced.

a beading-roller b3,

or may be provided with having a beading-flange bl. The roller h3 islikewise removably secured to the shaft B, so that it may-readi] y beremoved and replaced by other beading-rollers of a different diameter orshape.` The roller b3 is preferably thus removably secured to the shaftB by means of an eccentric groove b5, cut upon the inte- 6o rior of theroller b3, in which groove is placed a short pin or wedge D, whichoperates to tighten the roller Z13 upon the shaft B when the shaft B isrevolved.

D is the shaft of the upper or movable crimping-roller. The shaftD isjournaled in suitable bearings D D on a pivotal and'vertically slidingor adjustable bar or frame F. The shaft D is furnished with a removablecrimping-roller d, having a groove d and a 7o flange d2, adapted to litover and form a support for the end ot' thecan during the crimpingoperation. The roller d is secured t-o the .shaft D re ovablygfandpreferably by means of screw-thr rtds d3, the saine as the roller b toits shaft, the threads being right and left hand, as shown, to preventunscrewing. The shaft D is likewise provided witha beadingroller d4,having a beading-groove d5, corresponding to the beading-flange b4 onthe roller 8o b3. The roller d4 is removably secured to its shaft D, andpreferably by the same means as above described for securing the rollerb3 to its shaft B. The sliding and pivotal bar or frame is pivoted orjournaled upon a slid- 8 5 ing or adjustable block H, which is adj ustedup and down in the guide or slotted standard II by means of theadjusting-screw h, which is furnished with a hand-wheel h'. The front Yend of the bar or frame F moves up and down 9o in the guide or slottedstandard G. The upward movement of the bar or frame F is limited by anadjustable stop g, secured in the standard G by a set-screw g', whichenters depressions or recesses in the stop-barg. The front or free endof the pivotal and sliding or adjustable crimper-roll-carrying bar F isoperated so as to force the crimping-roller d against thecrimping-roller b by means of a treadle or lever K, which is connectedto the roc bar F by a linlt K. The link K is made in two partsadjustably connected together by a set-screw Zc,wl1ich passes throughthe sleeve part K2of thelink and engages the other part K thereof. Thepivotal and vertically-moving crimping-roller shaft D is driven from theshaft B by means of the gears P Pl on the shafts B and D, respectively,and the intermediate gears P2 P5, which are journaled on an arm or leverP4 pivoted to the shaftB, the free end of which is adjusted in properposition in relation to the distance between the shafts B D by means ofa slotted standard P5 and a set-screw p, which passes through the slot pof the standard P5.

T is a gage secured to the rod t, which is adj ustably fixed in theframe A by the setscrew if. The purpose of this gage is to afford a stopfor the end of the can to abut against during the crimping operation.

In operation a can-such as is represent-cd, for example, in Fig. 7-isplaced over the roller b, with its open end abutting against the gage T.The operator then, with his foot upon the treadle K, depresses theroller-carrying bar Fand forces the crimping-roller d against its mateb. At the same time and bythe same operation the beading-rollers d andb5 will form a bead in the can, if itis desired to bead the can also. Ifnot, the beading-rollers will of course be removed from the shafts B andD. To operate upon cans of larger diameters, the rollers b CZ and b5 b4will be replaced by other or similar rollers of a larger diameter. Thepivot-block H is adjusted to the proper height by means of a screw 71yto keep the shafts B D parallel when inoperation, the stop g and thelink K being also adjustable to suit the diameter of the can operatedupon. The gage T may also be adjusted in and out for operation upon cansof different lengths. By means of the eccentric groove and the fasteningpin or wedge for securing the beading-rollers in place on their shaftsthese beading-rollers may be secured at any position longitudinally ontheir shafts, so that the bead may be produced at any point desired inthe can. By moving or adjusting the lever P5 the gearing P P2 P3P4 willproperly mesh together whatever may be the relative position to whichthe shaftD is adjusted by its sliding pivot-block. For very small cansthe gears P and P may mesh directly together, the gear P3 beingthrownout of mesh by the lever P4. The pivotal frame or bar F is retracted bya spring 7s. The shafts B and D are provided with adjustable collars B2and D2, fixed in place by set-screws, so that the shafts B and D may beslipped longitudinally when necessary to accommodate cans of greaterlength: The shafts B and D are splined, so that the may slide throughthe gears P and P.

I claiml. The combination of frame A, shaft B, j ournaled thereon,furnished with a crimpingroller l), sliding bar F, its guides GH,sliding pivot-block H, adjusting-screw h, crimpingroller shaft B,journaled on said bar F and furnished with crimping-roller b,operatinglever K` adjustable connecting-link K', and an adjustable stopg, said shafts B and D being furnished with driving-gears, in termediategears, and a lever upon which said intermediate gears are journaled -foradjusting their position, substantially as specified.

2. The combination, with a crimping-roller and its shaft journaled infixed bearings, of a pivotal and vertically sliding or adjustablecrimping-rollerand its shaft, driving-gears o each of saidcrimping-roller shafts, and a lever carryingintermediate gears forcommunieating motion from one of said shafts tothe other in itsdifferent positions oradjustments, substantially as specified.

3. The combination, with a crimping-roller shaft B, journaled in xedbearings1 of crimpl ing-roller shaft D, journaled on vertically- 85 isliding and pivotal bar F, sliding pivot-block H, means for adjustingsaid block, an operati iig-lever having an adjustable connection withsaid pivoted bar F, driving-gears on said shafts B D, and an adjustablelever carrying intermediate gears, substantially as specified.

et. The combination,with a crimping-roller shaft B, journaled in fixedbearings, of crimping-roller shaft D, journaled on verticallysliding andpivotal bar F, sliding pivot-block H, means for adjusting said block, anoperating-lever having an adjustable connect-ion with said pivotal barF, driving-gears on said shafts B D, an adjustable lever carryingintermediate gears, and a gage for the end of the can to abut against,substantially as specified.
